After experiencing a cold gun failure, what is the first step to troubleshoot the weapon?

The first step to troubleshoot a cold gun failure, which typically indicates that the weapon did not fire when expected due to various potential issues, involves pulling the cocking handle to the rear and locking the bolt. This action is crucial as it ensures that the weapon is properly cocked and ready for another attempt to fire. By locking the bolt, you are also able to inspect the chamber to determine if there is a round present and to check for any obstructions or malfunctions that may have led to the failure in the first place.

This step is essential because it directly addresses the mechanism of the firearm, allowing the operator to ensure that it is functioning as designed. It sets the stage for any further troubleshooting, which may involve examining ammunition or conducting safety checks, but securing the bolt is foundational in resolving a cold gun failure.
